What two gases are vital to marine life?
Gases are also dissolved by seawater. Carbon dioxide(CO2) is dissolved in ocean water and used by phytoplankton to produce plant matter. Oxygen and nitrogendissolved at the surface from the atmosphere are also present in seawater. Conversely, the ocean also releases these gases into the atmosphere.

What is the thin blanket of gases and tiny particles that surrounds Earth?
The thin blanket of gases and tiny particles that surrounds Earth is called the atmosphere. It plays a vital role in protecting life by providing oxygen, regulating temperature, and shielding from harmful radiation.
Why did Earth's early atmosphere contained carbon dioxide sulfur dioxide hydrogen nitrogen water vapor methane and ammonia. These gases were present in the atmosphere primarily because?
These gases were likely present in Earth's early atmosphere due to volcanic activity releasing them, as well as impacts from asteroids and comets during the planet's formation. Chemical reactions between these gases played a vital role in the formation of the Earth's atmosphere as we know it today.
What is the envelope of gases that surrounds a planet like earth?
The envelope of gases that surrounds a planet like Earth is called the atmosphere. It is composed of layers of gases that are held in place by the planet's gravity, providing vital protection and support for life as we know it. The atmosphere plays a crucial role in regulating temperature, protecting against harmful radiation, and facilitating weather patterns.
What are 2 main ingredients in earth's atmosphere?
Nitrogen and Oxygen account for almost 99% of Earth's atmosphere.
what does the atmosphere and biosphere?
The atmosphere is the layer of gases surrounding a planet. It serves a vital role in regulating temperature and weather patterns. The biosphere is the region of Earth where life exists, including all living organisms and their interactions with the environment. It encompasses the atmosphere, hydrosphere, and lithosphere.
What is the gaseous portion of the earth?
The gaseous portion of the Earth is primarily composed of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases like argon, carbon dioxide, and water vapor. These gases make up the atmosphere, which surrounds the Earth and plays a vital role in supporting life.
If earth had no atmosphere would it be lifeless?
Yes. The atmosphere is a vital source of oxygen, water vapor, and carbon dioxide, all of which are necessary components of life. While it is technically not a source of these, it is a very important sink in which these gases are temporarily stored and cycled.
What is the layers of gases surrounding the earth?
The layers of gases surrounding the Earth are known as the atmosphere. These layers include the troposphere (closest to Earth's surface), the stratosphere, the mesosphere, the thermosphere, and the exosphere (farthest from Earth). Each layer has distinct characteristics and plays a vital role in supporting life on Earth.
What is atmosphere expling abaut?
The atmosphere is the layer of gases surrounding a planet, held in place by gravity. It plays a crucial role in supporting life, regulating temperature, and facilitating weather patterns. Earth's atmosphere is composed mainly of nitrogen, oxygen, and trace gases, and it protects the planet from harmful solar radiation. Additionally, it enables processes such as photosynthesis and the water cycle, which are vital for sustaining ecosystems.
What are gases such as carbon dioxide and methane called that help maintain the warm temperatures near the surface of Earth?
These gases are called greenhouse gases. They act like a blanket, trapping heat in the atmosphere and contributing to the Earth's greenhouse effect. They play a vital role in keeping Earth's temperatures suitable for life.
